Okie, it is not too hard.
Set these numbers a and b, notice a, b positive.
We have a+b=42.
You can see the next on my photo
Or you can use the formula of Cauchy
Answer:
46 mph
Step-by-step explanation:
Distance = speed x time
92 mi = speed x 2 hr
speed = 92/2 = 46 mph
Answer:
9.0×10^3K/moles
Step-by-step explanation:
ionization energy of these electrons = Energy of photons - kinetic energy of the electrons
Given
Kinetic energy of electron = 1.34×10^5
Energy of photons = 1.43 x 105 kJ/mole
Required
Ionization energy of these electrons
Ionization energy of these electrons = 1.43×10^5-1.34×10^5
ionization energy of these electrons = 0.09×10^5 kJ/mol
= 9.0 × 10^3 kJ/mol
Hence the ionization energy of these electrons is 9.0×10^3K/moles
